SPECIFICATION' forming part of Letters Patent No. 767,961, dated August 16, 1904. Application filed Apii124, 1903. Renewed December 16, 1903. Serial N o. 185,448. (No model.)

To @ZZ whom, it may concern:

Be it known that I, WILLIAM J. RUFF, a citiresiding in Quincy, in the countyof Adams and State of Illinois, have invented certain new and useful Improvewhich the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

The object of my present invention .is to produce a pasteurizer wherein the bottles of beer are submerged in a water-bath during the time th'at'they are subjected to the maximum temperature, while thepreliminary heating and final cooling of the beer is effected without having the bottles submerged in the bath, the result being that a' comparatively small amount of waterY is necessary to accomplish the work of pasteurization.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a side elevation illustrating my invention, the tank being shown in vertical section. Fig. II is a side elevation, the auxiliary tank being shown in vertical section. Fig. III is an enlarged detail section taken on line III III, Fig. I, and illustrating one of the stop-arms that act to turn the drain-pipes of the baskets or receptacles. Fig. IV is an enlarged detail section taken on line IV IV,

` Fig. II. Fig. Vis an enlarged detail top view,

part in section, showinga portion of the endless carrie. Fig. VI is a detail side view of the carrier. Fig. VII is an enlarged longitudinal section showing one of the regulators. Fig. VIII is a section taken on line VIII VIII, Fig. VI, and showing part of one of the baskets or receptacles and its drain-pipe.

In all .pasteurizers it is necessary to attemperate or warm the beer before it is submitted to the maximum temperature, and it is I p also necessary to cool the bottles off after they leave themaximumtemperature before they are subjected to the loutside atmosphere.

The object of my invention is to construct a machine ,wherein the bottles are submerged in a bath of maximum temperature, while the preliminary heating is effected before the bottles-enter this bath, and the final cooling is effected'after the bottles leave this bath, the

` result being that a comparatively small amount which hasa top extension, through which the carrier passes, to permit the bottles to be placed in their baskets or receptacles and to be removed therefrom, the bottles being inserted at A and removed from the carrier at B. The carrier consists of a pair of endless chains 3, between which the bottle-containing baskets or receptacles 4 are placed and to which the baskets are pivotallyy connected, preferably by means of stems or trunnions 5, that project from the ends of the baskets, as shown in Fig. pair of upper sprocket-wheels 6 behind a set of sprocket-wheels 7 8 at one end of the machine and behind a pair ofsprocket-wheels 9 at the other end of the machine, the sprocket- Wheels being secured to shafts 10, suitably journaled in the tank 1'.

11 represents guide-rails for directing the :movement of the carrier.

The tank l is supplied with water of suflicient depth to cover the underrunning part of the carrier, as seen in Fig. I, the water being supplied through means of a pipe 12. 13 represents an overliow-pipe to be used in case of too much water being let into the tank. This water in the lower part of the tank 1 is heated and maintained at the proper maximum temperature' for pasteurizing the beer (say at 148O Fahrenheit) through means of steam admitted to the tank through a pipe 14 and a jet-pump 15, such as is shown-in Fig. VI of my Patent N o. 607,776, dated July 19,

1898. The jet-pump connects with the tank through means of a lower pipe 16 and an upper pipe 17, the pipe 17 being preferably extended to the far endof the tank from the pump 15. 'When the pump is working, there V. The chains pass over av will be a circulation of water from'th'e upper 95 part of the body of waterin'thetank through the pump and into the lower part of the body ofwater.

18 represents a diaphragm-valve (such as is shown in Fig. VII of my Patent N o. 701,622,

roo

dated June 3, 1902) in the pipe 16 outwardly beyond the pump 15. i valve 18 may be automatically controlled to maintain a constant temperature of the water in the tank 1, I provide the regulator shown i-n Fig. VII. The regulator connects with the diaphragm of the valve 18 by means of a pipe 19. The regulator consists of a cylinder 20, secured to the wall of the tank 1 and having a tube 21, that extends into the tank. Within the tube 21 is a thermostatie bar or rod 22, the inner end of which is made Afast to the end of the tube, as shown at 23, Fig. VII. In the outer end of the cylinder 2O is fitted a plug 24, into which is tapped a stem 25, having a part 26, that communicates with the pipe 19. The inner end of the stem 25 forms the seat of a valve 27 on the outer end of the thermostatic bar 22.

28 is a compressed-air pipe tapped into the' plug 24 and which communicates with the in terior of the cylinder 20. When the temperature in the tank 1 falls below a given point, (say 148O Fahrenheia) the bar 22 will contract and open the valve 27. Compressed air will then pass through the pipe 28, which is connected to a suitable compressed-air tank (not shown) through the stem 25 and through the pipe 19 to the diaphragm-valve 18, thus causing the valve to be opened and starting up the jet-pump by the passage of steam through the pipe 14. When the temperature in the tank .1 is restored, the bar 22 will expand, closing the valve 27, thus stopping the action of the pump by shutting off the steam in the pipe 14. The stem 25 may be turned to adjust it inwardly or outwardly, so that the valve 27 will close sooner or later, thus enabling the' operator to provide for the exact temperature desired in the tank 1.

I make no claim as inventor to the construction of the regulator which I have described, and any desired form of regulator may be used.

3() represents a pipe communicating with the tank 1 below the waterelevel and whichl extends to one of the upper corners of the machine, where it is provided with branches 31 32, that are located over the bottle-carrier, as shown in Fig. I. In the pipe 30 is a rotary pump 33 of any ordinary well-known construction, driven by a belt 34 from a pulley on a shaft 35. When the machine is in operation, the pump 33 operates continuously and conducts'water from the lower part of tank 1 through the branch 32 of the pipe 30, from which it flows into the passing baskets of the carrier. A portion of the water passing through the pipe 3() escapes through the branch 31 of the pipe except when this branch is closed by an automatic diaphragm-valve 36, that corresponds in construction and operation to the valve 18. Tater escaping through the branch 31 is deposited in the passing baskets of the carrier. It will be noted that In order that thisthe carrrier moves in an upwardly direction toward the wheels 7 and as it leaves the wheels moves in a downwardlydirection. rl`he branch 31 of the pipe 30 deposits water into the baskets on the advance side ol the wheels 7, and

the branch 32 deposits water into the baskets on the other or retreating side ot the wheels 7. The stems o1' trunnions o'lt the baskets are made hollow, as shown in Fig. V, and they are connected together by means olE flexible pipe 38 and loose sleeves 39, the sleeves litting loosely on the trunnions, so as to be lree to l turn as the carrier passes around the sprocketwheels. The pipes may either be made ol flexible tubing, as shown at C, Fig. V, or be madeA of plain telescoping sections, as shown at D, or may be made olf sections ioined by a stuiiing-bex union, as shown at IC. 'lhe trunnions of the baskets are cormected together alternately at opposite ends ol the baskets, as shown, so that the water entering one end ol each basketpasses across the same and leaves at the other end, thereby pr ducing a circulation of water through the baskets. As the water enters the baskets through the branch 31 oi' the pipe 3() it circulates through the baskets, passing from one to another until it reaches the low point', which is at F, and will here overflow into a catch-basin 40, from which it passes to the auxiliary tank 41 through a. pipe 42, and the water entering the baskets through the branch 32 circulates from one basket to the next until it reaches the lowest part in the underrunning part oi the carrier, where it mingles with the water in the lower part of the tank 1. It will thus be seen that while the baskets are passing from the wheels 7 to the water-bath in the bottom olf the tank the bottles therein are subjected to the action of hot water, which is constantly circulated around them, and while the baskets are pass ing through the bath they are all the time subjected to the water o1'l maximum temperature, so that by the time the baskets reach the wheels 9 the beer has become thoroughly i'iasteurized. Extending from the auxiliary tank 41 to a` point near the supporting-wheels 6 ol the car rier is a pipe 46, provided with a rotary pump 47, driven from the sha'lit 35 by a belt 48. 'l`his pipe deposits water from the tank 41 into the baskets as they descend from the supportingwheels 6, and the water passes from one basket to another until it reaches the low point F ol the carrier, where it overiiows into the catchbasin 40 and passes back into the tank 41 through the pipe 42. rIhis water provides lor the initial warming of the beer, and it is maintained at the desired temperature by means ol water passing from the tank 1 into the baskets through the branch pipe 31, which, as stated, passes from one basket to another until it reaches the point F, where it overllows into the catch-basin and enters the tank 41. For automatically controlling the passage ol water through the branch pipe 31 .l provide the dia- IOO thus be seen that the temperature of the water in the tank 41 is utilized to control the Valve 36 and to admit water from the tank 1 to regulate the temperature of the attemperating or warming water in the tank 41.u

Forthe purpose of cooling the bottles of -beer while the carrier passes from the wheels 9 to the'wheels 6 I provide the pipe 46 with a branch 51, that terminates at a point near the Wheels 6 on the opposite side of the wheels to the point where the attemperatingwater is discharged into the baskets, as seen in Fig. I. This water circulates from one basket to another and cools off the beer in the bottles. It overflows from the baskets at about the surface of the water in the tank 1.' The pipe 51 is provided with a diaphragmvalve 52 of the same construction and operation as the valves 18 and-36. With this diaphragm-valve connects a compressed-air 'pipe 53, .provided with a valve 54, connected to a iioat 55, located in the tank 41. When the y water rises in the tank 41 after the machine has been started in operation, the float opens the valve 54 and -compressed air passes to and opens the valve'52 inthe pipe 51, thus permitting a flow of water through the latterv pipe to cool the beer.

It is apparent that when the use of the machine is to be temporarily stopped or stoppedL for atime being and it is desired to remove all of the bottles from the baskets that there' will be lesswater escaping from the baskets at the point F than when the machine isin full operation, this difference being equal to the amount of displacement caused by the introduction of fresh bottles into the baskets, which has now been stopped or discontinued, owing to the-fact that it is desired to empty the machine. This diminished flow of water finto the tank 41 must be compensated for,

for the reason that the use of cooling-water is required for some time after the insertion of bottles into the baskets has been discontinued. To compensate for this diminished flow of water, I employ a pipe 56, connected with a water-main or other source of supply and which is provided with a valve 57, connected toa float 58, located on the surface of the water in the tank 1. When the machine is in full operation, the oat is held in its raised position and keeps the valve 57 closed. When the flow of water from the baskets into the tank 1 is diminished by no more bottles being placed in the baskets, the fall of the water in the tank allows the float 58 to drop and open the valve 57, whereupon a flow of water passes through the pipe 56 into the tank 41, thereby ,keeping up a supply of water in the tank 41 for cooling purposes.

It is desirable to have the' baskets drained ofy water at the time that they reach the point where the bottles are taken from the baskets.l

To accomplish this, I provide each basket with a hollow stem 61 (see Fig. VIII) near its boty tom, upon which fits a sleeve 61, carrying a short pipe 62. Just before the baskets reach the wheels 6 these pipes come against a sta- 'tionary stop-arm 63,y (see Figs. I and IIL) causing them to be. turned from an upwardlyinclined to a downwardly-inclined position, so that the water willdrain from the baskets through the pipe 62 and fall into the tank 1.

As the baskets pass over the wheels 6 they are emptied and refilled with bottles, and as they are passing to a point beneath the pipe 46 the pipes 62 come against another stationary stop-arm 64 '(the same as the stop 63) and are moved from a downwardly-inclined to an upwardly-inclined position, thus shutting off the escape of water from the baskets.

65 represents a b'afiie-plate placed in thev tank 1 over the underrunning portion of the l carrier for the purpose of defiecting pieces of broken glass in case any of the bottles explode, such as sometimes happens.

In a machine thus constructed the beer is attemperated, submitted to a bath of water of maximum temperature, and cooled, all with the use of a very small amount of water as compared with what is ordinarily required Where the beer is attemperated, submittedto the maximum temperature, and cooled all in a bath of Water.
